The efficacy of bibliotherapy for mildly and moderately depressed older adults was examined. Cognitive bibliotherapy and behavioral bibliotherapy were compared with a delayed-treatment control condition. Results indicate that the two experimental conditions were superior to the control condition, but that the cognitive and behavioral bibliotherapies were nondifferentially efficacious. Sixty-six percent of the subjects demonstrated clinically significant change. There were no specific effects associated with either the cognitive or the behavioral interventions. Treatment gains were maintained at 6-month follow-up. The implications of bibliotherapy for geriatric depression as an alternative or adjunct to traditional treatments are discussed.
